This paper aims to provide a methodology for designing and conducting solvency stress tests, under the standardised approach as per IFSB-15, including the establishment of macro-financial links, running scenarios with variation of assumptions and stress scenario parameters; apply and illustrate this methodology by providing a stylised numerical example through a tractable Excel-based framework, through which Islamic Commercial Banks (ICBs) can introduce additional regulatory requirements and show that they would remain in compliance with all capital requirements after a moderate to severe shock; and identify the potential remedial actions that can be envisaged by an ICB.

The paper uses the data of the one of the groups to which certain amendments and related assumptions are applied to develop a stylised numerical example for solvency stress-testing purposes. The example uses a Stress Testing Matrix (STeM; a step-by-step approach) to illustrate the stress-testing process. The methodology of the paper uses a two-stage process. The first stage consists of calculating the capital adequacy ratio (CAR) of the ICB using the IFSB formulae, depending on how the profit sharing investment account (PSIA) are treated in the respective jurisdiction. The second stage is the application of the stress scenarios and shocks.

Taking into account the specificities of ICBs such as their use of PSIA, the results highlighted the sensitivity of the CAR of an ICB with respect to the changes in the values of alpha and the proportion of unrestricted PSIA on the funding side. The simulation also indicated that an ICB operating above the minimum CAR could be vulnerable to shocks of various degrees of gravity, thus bringing the CAR below the minimum regulatory requirement and necessitating appropriate remedial actions.

The paper highlights various implications and relationships arising out of stress testing for ICBs, including the vulnerability of an ICB under defined scenarios, demanding appropriate immediate remedial actions on future capital resources and capital needs. The findings of the paper provide a preliminary discussion on developing a comprehensive toolkit for the ICBs similar to what is developed by the International Monetary Fund Financial Sector Assessment Programme.

This paper focuses on the gap with respect to the stress testing of capital adequacy. The main contribution of the paper is twofold. The first is the development of an STeM – a step-by-step approach, which provides a method for simulating solvency (i.e. capital adequacy) stress tests for ICBs; the second is the demonstration of the potentially crucial impact of profit-sharing investment accounts and the way they are managed by ICBs (notably the smoothing of profit payouts) in assessing the capital adequacy of the ICBs.

The paper aims to gain an insight into the risk management tools practised in Islamic and commercial banks in Malaysia, and selected Islamic banks outside Malaysia. The study also examines the level of adequacy of risk management tools and systems of these banks.

The study employs primary data collected using a questionnaire survey.

There are significant differences in the level of extensiveness of the usage of market value at risk (VaR), usage of stress testing results, the usage of credit risk mitigation methods and also the level of extensiveness of the usage of operational risk management tools between Islamic and conventional banks. The findings further show that risk management tools and systems for Islamic banking are inadequate, particularly in the critical areas of “IT professionals with relevant expertise in process integration and risk analytics”, “IT systems to cater for each Islamic instrument” and also the “capacity of human capital in the highly technical areas of risk measurement.” This implies that more innovations and product developments are needed for Islamic banking in managing risks.

Since there are relatively few studies conducted in this area, specifically among Islamic banks in Malaysia, this study will broaden the scope of the literature by providing novel empirical evidence.

In line with the IFSB and BCBS methodology, the purpose of this study is to undertake a comparative analysis of dual banking systems for asset-liability management (ALM) practices with the duration gap, in Islamic Commercial Banks (ICBs) and Conventional Commercial Banks (CCBs). Based on the research objective, two research questions are developed: How do the duration gaps of ICBs compare with those of similar sized CCBs? Are there any country-specific and regional differences among ICBs in terms of managing their duration gaps?

The research methodology comprises two-stages: stage one uses a duration gap model to calculate the duration gaps of ICBs and CCBs; stage two applies parametric tests. In terms of the duration gap model, the study determines the duration gap with a four-step process. The study selected a sample of 100 banks (50 ICBs and 50 CCBs) from 13 countries for the period 2009-2015.

The paper provides empirical insights into the duration gap and ALM of ICBs and CCBs. The ICBs have more variations in their mean duration gap compared to the CCBs, and they have a tendency for a higher (more) mean duration gap (28.37 years) in comparison to the CCBs (11.79 years). The study found ICBs as having 2.41 times more duration gap compared to the CCBs, and they are exposed to increasing rate of return (ROR) risk due to their larger duration gaps and severe liquidity mismatches. There are significant regional differences in terms of the duration gap and asset-liability management.

Future studies also consider “Off-Balance Sheet” activities of the ICBs, with multi-term duration measures. A larger sample size of 100 ICBs with 10 years’ data after the GFC would be more beneficial to the industry. In addition, the impact of an increasing benchmark rate (e.g. 100, 200 and 300 bps) on the ICBs as per the IFSB 20 per cent threshold can also be established with the duration gap approach to identify the vulnerabilities of the ICBs.

The study makes profound contributions to the literature and suggests various policy recommendations for Islamic banks, regulators, and standard setters of the ICBs, for identifying and measuring the significance of the duration gaps; and management of the ROR risk under Pillar 2 of the BCBS and IFSB, for financial soundness and stability purposes.

To the best of the authors’ knowledge, this is a pioneer study in Islamic banking involving a sample of 100 banks (50 ICBs and 50 CCBs) from 13 countries. The results of the study provide original empirical evidence regarding the estimation of duration gap, and variations across jurisdictions in terms of vulnerability of ICBs and CCBs in dual banking systems.

This paper aims to introduce a model-based stress-testing methodology for Islamic finance products. The importance of stress testing was indeed clearly underlined by the adverse developments in the global finance industry. One of the key takeaways was the need to strengthen the coverage of the capital framework. Cognisant of this fact, Basel III encapsulates provisions to enhance the financial sector’s ability to withstand shocks arising from possible stress events, thereby reducing adverse spillovers into the real economy. Similarly, the Islamic Financial Services Board requires Islamic financial institutions to run stress tests as part of capital planning.

The authors perform thorough backtests on Islamic and conventional portfolios under widely used risk models, which are characterised by an underlying conditional volatility framework and distribution, to identify the most suitable risk model specification. Associated with an appropriate initial shock and estimation window size, the paper also conducts a model-based stress test to examine whether the stress losses estimated by the selected models compare favourably to the historical shocks.

The results suggest that the model-based framework, when combined with an appropriate risk model and distribution, can successfully reproduce past stress periods. The conditional empirical risk model is the most effective one in both long and short portfolio cases – particularly when combined with a long-enough estimation window. The relative performance of normal vs heavy-tailed distributions and symmetric vs asymmetric risk models, on the other hand, is highly dependent on whether the portfolio is long or short. Finally, the authors find that the Islamic portfolio is generally associated with lower historical stress losses as compared to the conventional portfolio.

The model-based framework eliminates some of the key problems associated with traditional scenario-based approaches and is easily adaptable to Islamic finance.

The purpose of this paper is to examine the relation “diversification-risk-performance” for Islamic and conventional banks in different financial stress levels. Also, it aims to investigate the impact of the structure of board directors, macroeconomic variables and banking specific factors on banking diversification.

The authors use generalized least squares regressions to examine the impact of banking specific, macroeconomic and governance variables on investment diversification of 66 Islamic and conventional banks during the period from 2006 to 2018. In addition, this study uses panel threshold regressions to study the impact of banks’ profitability and risks on investment diversification in different financial stress levels.

The findings show liquidity risk, performance, credit risk and capitalization ratio are significantly related to investment diversification of Islamic banks. On the other hand, liquidity and credit risks, capital to total assets ratio and size have a significant influence on investment diversification of conventional banks. In addition, the diversification strategy of Islamic banks is less sensitive to macroeconomic indicators. As regards to governance variables, the results suggest that the board size, the executive directors and the foreign directors have significant impact on the investment diversification in Islamic banks. On the other hand, chief executive officer duality and foreign directors affect significantly the investment diversification of conventional banks. This study also found that financial stress enables us to develop a better understanding of the relation “performance-risks and diversification.”

It is expected that the findings of this paper can be used by Islamic and conventional banks in Gulf Cooperation Council (GCC) region that seek to manage the diversification strategy by reducing risk-taking and maximizing profitability. This study suggests that bank managers should consider the level of financial stress during the development of diversification strategy. It provides a better understanding for bank managers about the effect of bank specific and macroeconomics factors as well as governance variables on diversification.

This study focuses on providing an extension of the existing literature by studying the impact of financial stress indices on the relation between banks’ risk-performance and investment diversification for Islamic and conventional banks in the GCC region.

This paper aims to examine and compare the impact of foreign direct investment (FDI) inflows on bank deposits in aggregate as well as at the level of conventional and Islamic banks in Middle East and North Africa (MENA) countries. The study also tests hypotheses of direct and indirect impacts of FDI flow and FDI stock on bank deposits.

Static and dynamic panel generalized methods of moments (GMM) estimation techniques are applied to analyze a large data set of 491 commercial banks (422 conventional banks and 69 Islamic banks) across 18 MENA countries between 1993 and 2017 (12,275 year observations).

Empirical results indicate that inflowing FDI flow and FDI stock have a significant negative direct impact on deposits of MENA banks. The results lend support for the direct channel hypothesis for the effect of FDI on bank deposits and find no evidence in support of the indirect channel hypothesis. FDI inflows affect bank deposits directly via increased FDI-related excessive competition in the banking market. Deposits from conventional banks appear to be more affected than those from Islamic banks. The variation may due to the fact that Islamic banks have fewer multinational corporations (MNC) customers than conventional banks and therefore are less sensitive to fluctuations in FDI.

From this analysis, this study concludes that foreign investments have a higher productivity than local investments in MENA region. Attracting more FDI is aimed at increasing overall national productivity through competition. However, governments would be wise to enact such a policy to maximize benefits and minimize potential harm to local industry. Furthermore, FDI policy should encourage small to medium-size banks and firms (SMEs)’ participation and linkage with multinational banks and MNCs, while upgrading research and development institutions and innovation activities to help SMEs to benefit from potential spillovers from foreign presence in the industry. In addition, the linkage and connection between SMEs and foreign firms should be strengthened and promoted by government policy.

This study is the first of its kind to examine the effect of FDI inflows on bank deposits. It also provides an in-depth quantitative analysis of the impact of FDI flow and FDI stock, separately, on bank deposits for both conventional and Islamic banks. It distinguishes between direct and indirect channels through which FDI inflows may affect bank deposits. The study analyzes 25 years of panel data for 491 banks (12,275 year observations) and uses both static and dynamic panel GMM estimation techniques to analyze the data.

The purpose of this paper is to examine and compare the impact of oil and gas prices shocks on the non-performing loans (NPLs) of banks at the aggregate as well as at the level of commercial and Islamic banks in Qatar over the period 2000-2016.

Using the West Texas Intermediate Database, BankScope Database, World Bank’s World Development Indicators Database, and International Monetary Fund Database, the authors use a one-step system generalized method of moments dynamic model to examine and compare the association between oil and gas prices shocks with NPLs in Qatari banks. The authors also test the hypotheses of direct and indirect impacts of oil price shocks and gas price shocks on bank NPLs.

The results indicate that oil price shocks and gas price shocks do not have directly affect NPLs of Qatari banks at the aggregate level, while they have indirect effects that are channeled through the country-specific macroeconomic and institutional factors. The authors find that oil and gas prices shocks affect NPLs of Qatari Islamic banks directly through extended oil and gas-related cash flows, while their impact on the NPLs of Qatari commercial banks is indirect. In other words, Islamic banks in Qatar greatly benefits from increased cash flow caused by the rise in the oil and gas prices, which make their NPLs, much lower than that in commercial banks. Better capital cushion, better managerial efficiency, better risk management, and liquidity management systems should be used by the Islamic banks in Qatar to expand their customer base. The authors also find that positive fiscal stance of the government reduces the NPLs in both commercial and Islamic banks.

The results of this study necessitate policy measures that can counter the effects of changes in oil and gas prices on the growth of bank NPLs.

It is widely recognized that oil and gas prices and the level of production are of great importance to the economic development of oil and gas-exporting countries. So far, however, no econometric study has been reported in the literature which analyses and compares the impact of oil and gas prices shocks on the NPLs of commercial and Islamic banks and also at the aggregate level in any of the oil economies. Thus, this study provides the first empirical evidence on distinct direct and indirect channels through which oil and gas prices shocks may affect bank NPLs.

The purpose of this study is to investigate the influence of capital adequacy ratio (CAR) prescribed in Basel III on the risk-taking behaviour of Islamic and conventional commercial banks in Malaysia. It also investigates the claim that the risk-taking behaviour of Islamic banks (IBs) and conventional banks (CBs) managers is identically influenced by CAR.

Secondary data for all CBs operating in the Malaysian banking sector are gathered from FitchConnect database for the 2011–2017 period. Both dynamic ordinary least squares and generalised method of moments techniques are used to estimate a panel data of 43 commercial banks, namely, 17 IBs and 26 CBs.

The findings of this study lend support to the favourable influence of CAR set in Basel III accord on risk-taking behaviour of both types of banks. CBs appeared to be remarkably better off in terms of capital buffers. Evidence is established on the identicality of the risk-taking behaviour of IBs and CBs managers under CAR influence.

Even though a high CAR is observed to hamper risk-taking of banks, the findings may serve as a signal to regulators to be mindful of the implications of holding a high CAR. Similarly, managers may capitalise on the findings in terms of strategising for efficient use of the considerable capital buffers. Shareholders are also concerned about managers’ use of the considerable capital buffers.

This study is among a few studies that endeavoured to provide empirical evidence on the claim that IBs mimic the conduct of CBs in light of the influence of CAR prescribed in Basel III on risk-taking behaviour, particularly banks operating within the same banking environment.

The financial system plays an essential role in facilitating the intermediation process for economic growth. Policymakers stress on achieving a well-developed and regulated financial system to achieve economic development and resiliency. Using data from the State of Qatar, this paper aims to examine the impact of financial development indicator on economic growth; the impact of financial development indicator on hydrocarbon and nonhydrocarbon sector; the impact of Islamic banking on hydrocarbon and nonhydrocarbon economic growth.

The research uses quarterly data from 2007 to 2019 and adopts autoregressive distributed lag cointegration techniques to test the long- and short-run dynamic relationship between various measures of financial development and economic growth.

The results present evidence of long-term cointegration between overall financial development indicator and economic growth. Furthermore, the authors document the existence of long-term relationship between financial development and nonhydrocarbon sector. However, there is a lack of evidence on the long-run relationship between financial development and the hydrocarbon sector. Notwithstanding, Islamic banking contributes to overall economic development, as well as to the nonhydrocarbon sector.

This paper offers policymakers with insights to evaluate measures to diversify the economy. It also assists decision-makers in promoting Islamic finance, particularly to the banking sector as a vital contributor to economic growth.

To the best of the author’s knowledge, this paper is the first to evaluate financial development and economic growth for the case of Qatar in light of recent developments in Islamic finance.

The purpose of this paper is to investigate and compare the impact of oil and gas prices changes on bank deposits at the aggregate as well as at the level of commercial and Islamic banks in Qatar over the period 2000–2016.

Using the BankScope Database as well as bank-level balance sheet and financial statements data, the authors use one-step system GMM dynamic model to examine and compare the association between oil and gas prices changes with bank deposits in Qatar. The authors also test hypotheses of direct and indirect impacts of oil and gas prices changes on bank deposits.

The results indicate that oil and gas prices changes have a direct impact on deposits of banks at the aggregate level in Qatar. However, the authors find that oil and gas price changes significantly affect deposits of Qatari commercial banks directly prompting enhanced lending by banks and the consequent business activities in the economy, while their impact on the deposits of Qatari Islamic banks is indirect, i.e. the impact is permeated through the macroeconomic and institutional characteristics of the country that are reinforced by the growing expectations and commercial sentiment of the country. The authors find that significant association between oil price changes and deposit growth during the global financial crisis 2008 has been distorted. However, the authors find that there was a sharp rise in the deposits of Islamic banks during the period of global financial crisis.

The results of this study necessitate policy measures that can counter the effects of changes in oil and gas prices on the effectiveness of bank deposits.

It is widely recognized that oil and gas prices and the level of production are of great importance to the economic development of oil and gas exporting countries. So far, however, no econometric study has been reported in the literature which analyses and compares the impact of oil and gas prices changes on bank deposits of commercial and Islamic banks and also at the aggregate level in any of the oil-exporting economies. Thus, this study provides the first empirical evidence on distinct direct and indirect channels through which oil and gas prices changes may affect bank deposits.
